Really needs more uses for alloys, maybe that unlock later in the game? As soon as I had access to Alloys I was able to afford every single upgrade with them. The e40 parts seem to slow way down and im not looking toward doing the e48 parts especially considering im only getting about 0.38x per reset and hitting that number about 10s into my runs. (Yes i could wait longer, but its not optimal, as it adds about 1.3x after about 10mins)
Solar Sails and Drone bay seem kinda useless, I've tried a ton of variants and only Extractor-Collector/Resonator-Extractor is efficient. Needs some way to make the two useful.
